Oh boy.
Good luck with the process. Your "dealer" should be able to point you a little better in the right direction, three important things to note:
1. You probably have a Certificate of Origin and not a Title.
2. As of Jan 2007 the procedure in PA changed and they limit the shops who can inspect "Specialty Constructed Vehicles" it is my understanding that in the change you are now required to have a real defroster setup (the plug in style is no deemed an obstruction of vision so that is no longer acceptable).
3. Search on here for Penndot and also checkout
